How to get rid of roaches for good?

Cockroaches are probably the most common pest that you may come across in your home space and they are definitely not that easy to get rid-off. These pests although tropical in origin can even be seen in the temperate zones across the globe.

World Health Organization (WHO) terms roaches as "unhygienic scavengers in human settlements" and that pretty much defines how annoying it can be to have roaches running around in your kitchen, attic, or in your entire home space.

Where there is food, there is bound to be roaches! They live in groups, are active during the night time, and live in spaces where there is considerable moisture, warmth, and food, which could basically be your home.

They normally venture in the night to search for food in food storage places, kitchens, rubbish bins, and even sewers and drains.

Cockroach Infestation problem in the House

How big is the cockroach problem? The first question to ask is – how did I get a roach in my home?

The only thing that attracts these extremely resilient pests to your home is food.

Sometimes your food storage areas may look clean on the outside but when you are fast asleep, the same place turns into an insane "all night party" place for the roaches.

Guess what? These pests can actually survive for a period of 3 months without eating.

What makes the situation bad is that it can be quite hard to find them.

They hide in just about any nook and corner of your home. If there are any dark, damp, and wet places in your home then that is definitely the best hideout for roaches.

The common hiding spots of roaches include:

  • Confined spaces including behind boxes and utensils and under refrigerator
  • In unused cardboard boxes, and under magazines or newspapers
  • Under fixed furniture
  • Cracks in walls
  • Kitchen cupboards
  • Around water purifiers or heaters
  • Below sinks
  • Around drains
  • Garden

Why you should get rid of cockroaches from your house?

Once a roach moves into your home, then it will invite others, and they will hatch hundreds and thousands of eggs and you will end up with a full blown infestation. A female cockroach can lay almost 10 to 40 eggs at a time and lays almost 30 batches of eggs within her lifetime. Normally a cockroach can survive for a period of 12 months.

Roaches are not just smelly pests that have the capability to cause a large infestation in a short time but what makes a roach infestation a really bad idea is that they can be carriers of several diseases.

Cockroaches are known to spread a variety of diseases although they are not considered to be direct vectors of such diseases. They only act as a reservoir. Transmission takes place when someone consumes items contaminated by cockroaches.

Cockroaches are known to be the carriers for organisms that can cause the following medical conditions:

  • Typhoid Fever
  • Salmonellosis
  • Cholera
  • Dysentery
  • Giardia
  • Gastroenteritis
  • Leprosy
  • Campylobacteriosis
  • Plague
  • Listeriosis

They are also known to trigger asthma as well as other allergies and are instrumental in spreading Staphylococcus aureus, E.coli, and Streptococcus.

Hence, it is extremely important to get rid of cockroaches as soon as you spot an infestation.

First line of Action: Cleaning, Sealing and Fixing leaks

The first line of action after you spot an infestation is to start by cleaning, sealing and fixing leaks or cracks in the walls. This is a 3-way process and includes:



Roaches are there in your home in the first place because they are attracted to food or food residue and especially grease.

So, the first step is keeping your home and especially the kitchen and food storage area clean.

This simply means that each night you will need to wipe counter and countertop, clean dishes, sweep floors, and just about sweep through the food storage area.


The next step is to seal up those nasty cracks in the walls.

Whether the cracks or holes exist on the kitchen walls or between the countertop and the wall, they are practically the home for roaches as well as other insects. You can use a caulking gun or a caulking tube to do the sealing job.

Fix leaks:

Fixing Leaks

Cockroaches tend to live or hide in areas where there is higher moisture content and water and that includes leaking pipes.

This is one of the reasons why you will find them in large numbers right under your kitchen sink. They can survive for long durations without food but they will not be able to survive too long without water. Hence, it is important to repair the leakages.

Second line of Action: Baits, Spray and Insecticides

Once you have taken care of the leakages and cracks it is time to move onto the second line of action, which is to get rid of the roaches once and for all!

You have to kill them or remove them from your premises otherwise they will keep laying eggs till you have an uncontrollable infestation on your hand.

So what are the ways?

​There are three important processes through which roach elimination is possible. They are:

​Cockroach Baits

Baits have been in use for a long time for extermination of roaches and they are still one of the best ways. The effectiveness of this type of pest control method exploits the coprophagic, cannibalistic, and emetophagic tendency of roaches. The baits are available in gel, liquid, or solid form and can be categorized as under:

Gel Bait:

Gel bait as the name suggests comprises of a gel mixture with the primary ingredient being an attractant as well as a killing agent. It is most commonly applied using a syringe although aerosol cans and bait gun tubes can do the job as well.

Gel baits are highly economical, stay moist for a longer duration, can be applied with ease, and is recommended for smaller home infestations.

Granular Baits:

These baits are available in granular form and are meant to exterminate bigger outdoor roaches in attics, void spaces, and basement. The granular baits can cover a larger area but they cannot be exposed to moisture or water.

Bait Stations:

These have been created primarily for indoor applications and comprise of a pesticide (killing agent), an attractant, and the station itself, which is an enclosure holding the attractant and pesticide. The most commonly used killing agent in bait station is boric acid and Fipronil. These stations are made from plastic or cardboard or a mix of both.

Roach Spray:

The cockroach spray is one of the effective ways of getting rid of the infestation. Some of the sprays are repellants while others are exterminators.

The roach spray is available in different quantities and depending on your need like indoor area or perimeter treatments around structures, you can invest in the same.

The primary ingredient in sprays are normally toxic in nature and may include Fipronil, Avermectin, Borates, Neonicotinoids, and Pyrethroids among others.

Insecticides to kill roaches:

Insecticides are one of the best roach killers on the market, But they are mostly highly toxic in nature due to their chemical composition and may cause mild harm to the eyes, nose, or skin when using them.

At the same time, they are highly effective in wiping out entire population as well as inhibit the life cycle of roaches. They can be categorized as under:

Insect Growth Regulator (IGR):

Insect Growth Regulator is a chemical substance that interferes with the life cycle of roaches and other pests. They help largely in controlling large populations or infestations and inhibit the growth of roaches. They are often used as a stand-alone product or with other insecticides.

They are available in the form of aerosol sprays and impregnated materials.


Neonicotinoids is a new class of insecticides that affect the central nervous system of roaches, which resulting in paralysis and death. The most commonly used Neonicotinoids include acetamiprid, imidacloprid, dinotefuran, clothianidin, thiacloprid, nithiazine, and thiamethoxam. They are available in the form of gels, aerosol spray, granular solutions, and impregnated materials.


Pyrethroid is an insecticide that is an active ingredient in over 3,500 registered pest products. They are synthetic chemical insecticides and considered to be highly toxic to aquatic organisms. They work by preventing the closure of the voltage-gated sodium channels in the axonal membranes, which leads to paralysis in roaches and ultimately causes death.

Some of the commonly used Pyrethroids include Permethrin, Allethrin, Cyfluthrin, Tralomethrin, Bioallethrin, Cypermethrin, Esfenvalerate, Deltamethrin, Tetramethrin, and Cyhalothrin. They are available in the solution, granular, and aerosol form.

Third line of Action: Experts to exterminate roaches

Got a large infestation of roaches that you can’t handle? Call in the experts, most commonly known as the exterminators.

Why do you need the experts?

Most often than not, it can be quite a tricky and complicated affair to ensure your home is completely rid of roaches especially when there is a large infestation. At such a time, a single type of treatment like spraying insecticide or cleaning doesn't work.

The only thing that will work is a "complete solution" that combines all the roach extermination methods. This is exactly the reason, professionals need to be hired.

Some of the benefits of calling in the professionals are:

  • They possess knowledge of different type roaches that may be causing havoc like American cockroach, Oriental, Smoky brown etc.
  • Based on the identification of the type of infestation, they can provide tailored solution for your home.
  • They will not only aid in exterminating roaches but also use some of the state of the art eradication methods and products to destroy their nest and disrupt the life cycle.
  • The roach extermination experts will also schedule follow-up visits to ensure a "roaches free" zone.
